Esp32 can bus work only on some boards
Posted: Thu Jun 20, 2024 9:10 am
I have a lot of esp32 dev boards, of some different makers, but all with the same esp32-wroom.
I’m try to read some can bus informations of my car.
I can make the sn65hdv work in 2 boards but not in the others the same code is not working, I try different can modules. Vp230…vp232.. different can libraries. Different pins…. Arduino ide.. platformio…
And the always the same result =\
The rest of the code work in all the boards. The oled display, buttons and leds. But only in 2 boards the can module works.
I try to upload the firmware. And the results was the same.
The only difference I noted is one of the boards that the can module work, I have to hold the boot button to upload the code.
Any one have a idea why the same code and the same can module works in one dev board but not in the other?
